1.功能描述

百度地图api抓取POI点（上海公交站）

2.代码

import pandas as pdimport requestsimport jsonimport numpy as npimport requestsurl = "http://api./place/v2/search?query=公交车站&region=嘉定区&" \"output=json&ak=KpPZdbZn9sGqSDZKSIyKki5O4sf7cL2S&page_size=20" #//GET请求#&page_size=20&page_num=3#print(url)res = requests.get(url)jd = res.json()jddname = jd['results']#①Station = []for station in jddname:#②a ={}name = station['name']lng = station['location']['lng']lat = station['location']['lat']a['name'] = namea['lng'] = lnga['lat'] = latStation.append(a)print(Station)

3.解读与注意

3.1对dict索引

打印jd

jd是dict，对dict索引：jd['result']

3.2对列表索引

打印jd['result']

可以看到这是一个list嵌套dict，注意这种哈，一定len一下看看是不是[]只有一个元素，那就索引jd['result'][0]把dict弄出来，否则，就要循环提取了，看②

3.3参数问题

注意一次只能抓取20条，后面再改进
